The Hankook Winter IPike W409 tire is the latest generation of winter tire optimized for safety and security on ice, snow, slush and wet roads on all types of cars, trucks and SUVs. The wide square tire profile dramatically improves the amount of rubber in contact with the road surface for better handling. The tread is heavily siped with lots of grooves. The tread has a solid center rib that fans out in a chevron shape that helps to evacuate snow and water to prevent slipping and hydroplaning in adverse weather. Also, the sidewall is stiffer for immediate feedback and response to steering input by the driver which improves the handling on dry cold winter roads.

The load index (LI) is a 2 or 3 digit number that corrolates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximim load of 1,201 lbs. In the case of our example the 87 identifies the tires ability to carry a maximum of 1,201 lbs. So 4 tires will carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimim Load Index. It is not recommended to install tires with a lower Load Index. By doing so, this could cause your tires to be overloaded thus potentially causing a blowout.... read moreread less

Speed Rating

T

Speed Ratings (SR) are based on laboratory tests and indicates the maximum speed the tire can achieve. These tests are based on limited time trials. Higher speed rating tires typically will yield better handling capabilities, but may often result in lower mileage. Refer to your vehicle owner's manual for the recommended minimum Speed Rating. It is not recommended to install a tire with a lower speed rating as it could affect the handling of your vehicle. It is important to note that speed ratings only apply to tires that have not been damaged, altered, under-inflated or overloaded. Additionally, most tire manufacturers maintain that a tire that has been cut or punctured no longer retains the tire manufacturer's original speed rating, even after being repaired because the tire manufacturer can't control the quality of the repair.... read moreread less

Ply Rating

Not Available

Ply Rating is related to the max load capacity. This value can be defined with a letter or number. The higher the number/letter, the higher the load capacity.

UTQG

Not Available

To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires). Click here for more information.... read moreread less

Max Single Load(lbs)

1477

The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index.

Max Single Air Pressure(PSI)

44

The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle.

Tread Depth

12.5

The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds.

Rim Width Range

5.5-7.5

The approved wheel rim width range this tire will support.

Measured Rim Width

6.0

The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.

Section Width

8.2

The measurement from sidewall to sidewall.

Tread Width

6.8

The measurement from one side of the tread to the other side of the tread.

Overall Diameter

25.5

The height of the tire when fully inflated.
